Please note:
Pins 5, 6, 7, 8, 13 and 15 are for external use to break/make
contacts in response to a configurable event in the unit. For example
these relays can be used to replicate the alarm conditions for the Main
and Auxiliary inputs. Options for these relays may be configured using the
web based GUI. The operation of Relay 1 and Relay 2 can be re-configured
through the Configuration>Remotes web page.
By default Relay 1 is set as the Main alarm and will alarm on either Main
left or Main right - in the alarm state pin 8 closes to pin 15 and pin 7 is
open. Relay 2 is set as the Aux alarm and alarms on Aux left or Aux right -
under the alarm condition pin 6 closes to pin 14 and pin 5 is open.
Pins 2, 3, 4, 10 and 11 are to replicate the switches and indicators for the
Source Select, Mode and Restore functions.
Note: The remote source select, pin 10, may be held low in order to force
the unit to route stereo input source B to the outputs.
Pins 1 & 12 are Ground and +5V respectively and can be used to source up
to 200mA of current to power external circuitry such as LED indicators or
relays.
Pin 14 is to select remotely a silence time of 2 minutes and 5 seconds. This
may be useful for the broadcast of Remembrance Day services, or where
you expect a silence of up to 2 minutes to be broadcast. The maximum
silence time is set whilst the contact is latched.
Pin 9 is used to remotely start an external piece of equipment and operates
on audio fail.
GPI/O Connector
There are 6 GPI pins available on a 9 way female D-type connector located
above the Remote Alarms Connector. These pins have been included to
provide more customised behaviour of the RB-SD1IP which could enable
non-networked hardware to generate alarms for an existing Network
Management System by using the network interface of the RB-SD1IP.
Currently each of the GPI pins can be used to trigger one or both of
the relays available to the Remote Alarms Connector. Each GPI can also
generate SNMP traps to follow pin activity.
Power and ground connections are available on this connector from the
same source as the 200mA +5V fused supply on the Remotes connector.

Ethernet Connector
The unit supports 10/100 Mbps Ethernet via a standard RJ45 connector.
The Green LED shows link status/activity and the Amber LED indicates
connection speed (On = 100 Mbps, Off = 10 Mbps).
A Webserver is built into the RB-SD1IP to allow easier configuration and
remote operation.
